Betula platyphyllaBetula platyphylla, the Asian white birch or Japanese white birch, is a tree species in the family Betulaceae. It can be found in subarctic and temperateAsia in Japan, China, Korea, Mongolia, the Russian Far East, and Siberia. It can grow to be 30 metres (100 feet) tall.

Invasive speciesAn invasive species is an introduced species that harms its new environment. Invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. Since the 20th century, invasive species have become serious economic, social, and environmental threats worldwide.
Pioneer speciesPioneer species are resilient species that are the first to colonize barren environments, or to repopulate disrupted biodiversesteady-stateecosystems as part of ecological succession.
BetulaceaeBetulaceae, the birch family, includes six genera of deciduousnut-bearing trees and shrubs, including the birches, alders, hazels, hornbeams, hazel-hornbeam, and hop-hornbeams, numbering a total of 167 species. They are mostly natives of the temperate Northern Hemisphere, with a few species reaching the Southern Hemisphere in the Andes in South America. Their typical flowers are catkins and often appear before leaves.
CatkinA catkin or ament is a slim, cylindrical flower cluster (a spike), with inconspicuous or no petals, usually wind-pollinated (anemophilous) but sometimes insect-pollinated (as in Salix). It contains many, usually unisexual flowers, arranged closely along a central stem that is often drooping. Catkins are found in many plant families, including Betulaceae, Fagaceae, Moraceae, and Salicaceae.
SpeciesBasic unit of taxonomic classification, below genusThe hierarchy of biological classification's eight major taxonomic ranks. A genus contains one or more species. Minor intermediate ranks are not shown.A species (pl. species) is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity.
CultivarA cultivar is a kind of cultivated plant that people have selected for desired traits and which retains those traits when propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human manipulation, but some originate from wild plants that have distinctive characteristics.
Glossary of leaf morphologyThe following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). The edge of the leaf may be regular or irregular, and may be smooth or have hair, bristles, or spines. For more terms describing other aspects of leaves besides their overall morphology, see the leaf article.
TriterpeneTriterpenes are a class of terpenes composed of six isoprene units with the molecular formula C30H48; they may also be thought of as consisting of three terpene units. Animals, plants and fungi all produce triterpenes, including squalene, the precursor to all steroids. StructuresTriterpenes exist in a wide variety of structures. Nearly 200 different skeletons have been identified. These skeletons may be broadly divided according to the number of rings present.
Traditional medicineTraditional medicine (also known as Indigenous medicine or folk medicine) refers to the knowledge, skills, and practices rooted in the cultural beliefs of various societies, especially Indigenous groups, used with the intent of treating illness and maintaining health. Traditional medicine includes systems like Ayurveda, traditional Chinese medicine, and Unani.
Family (taxonomy)Family (Latin: familia, pl.: familiae) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus.
DeciduousIn the fields of horticulture and botany, the term deciduous means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; To the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of deciduous in the botanical sense is evergreen.
